Intro
The second generation of Burson opamp was developed in collaboration with some of the world’s most passionate musicians, sound engineers and
recording artists. This project has taken two years to complete, with an end result reaching beyond our greatest expectations of musical
reproduction. Its qualities have been pushed to the very frontier of studio technology. Like a photographer’s latest favourite lens, it is being
utilized by recording artists around the world, to better capture the moments that last for an eternity

The Angry Realization
The function of Opamps at the output stage is as important as the lens on a cinema projector. Regardless of the
analytical capability of the audio gear, an inferior opamp will halve a machine’s performance, and distort every dB of
sonic imagery.
For fellow audio enthusiasts, there inevitably comes a time to explore opamp upgrades for their equipment. After
hopping from forum to forum, and checking every pricelist, it’s all too easy to become confused with the subsequent
findings. That humble pair of IC opamps in their machine is worth less than a can of coca-cola. Replacing them with
another pair of IC opamps, worth a little less than a McDonalds burger will noticeably improve the overall performance of
their mega dollar machines.
One question then burns in the minds of such audio enthusiast;
How could the manufacturer’s, with their respectable brand, history, and self proclaimed team of world leading audio
scientists not know that a simple opamp switch could lift the performance of their product? Why wouldn’t they have
adopted “that” opamp initially, when their production costs would be increased by only 1%.
Then comes the incredibly infuriating realisation that the manufacturers would have known this all along! Unfortunately
however, their focus is solely on profit. Even after pricing the machine with a large profit margin, a profit driven
manufacturer will never hesitate to continually lower their production cost at the expense of quality sounding music!
Then, after paying a very high price for what is presumably a respectable piece of equipment, a passionate audio
enthusiast still has to risk it all by tweaking their machine with a soldiering iron.
It may be true that we live in a profit driven world now, but when the promise of a high calibre sound system falls short,
and excellent sound quality music is the victim, it still angers us all!

The Whole Truth
Unfortunately, that is not the whole truth. The whole truth about IC opamps is that they are in that machine for one
reason and one reason only. It is simply a cost saving exercise at the expense of high calibre sounding music!
ICs are cheap and sticking an IC opamp onto a PCB simplifies the entire design, assembly and quality control
process. However, IC opamps have countless faults that make them unsuitable for audio application. Below are just
some of them.
IC Opamps are not designed with a focus on Audio.
IC opamps are highly inconsistent in quality:
IC opamps are poorly conducted and degrades musical signal at all level
IC opamps suffer from EMI noise

Burson Audio opamp
We at Burson Audio have realised the inferior quality of IC Opamps for quite some time.
We love music and it’s always been our philosophy to enhance sound quality wherever possible. We’
re aware that the only way to overcome the IC opamp problem, is to replace them with a well
designed discrete circuitry.

Building the Burson opamp
The team at Burson Audio has been developing the Burson opamp project for a number of years now. From the first version to the current
production, improvement has been made along the way, as part of the quest for perfection.
The foundation of the Burson Opamp is a sophisticated Voltage Differential Amplification network. The entire opamp is constructed from audio graded
transistors and resistors. Such a design will ensure minimal colouration and maximum dynamics, but this design feature also posed a great challenge
to production; without rigid component matching, it would be easy for sonic imbalance to occur.
An easy solution to the above problem would be to add a blue trim pot in our design. This would allow for adjustments to be made to accommodate
for any imperfections in the component matching. But we weren’t prepared to accept the signal loss that would come with such an approach.
Instead, we employed the BURN and MATCH procedure. We only use a 1% tolerant resistor. Before soldering them onto the PCB, we put them
through a component burn-in module. After 50 hours of burn-in, each resistor will then be retested and matched before proceeding to our assembly
line. The result of such a quality control process, is a further 10% of component rejection. This strict and very expensive BURN and MATCH
process ensures the stability of the circuit. It ensures a perfect balance of sonic imagery across the entire frequency spectrum. It also guarantees a
stable and realistic sound stage between the speakers.
Furthermore we insisted on a top quality lead free solder and temperature controlled soldering process. This was the only solution to reducing heat
stress on our components, and minimising short circuits caused by a soldering bath used in large-scale production.
Cost focused manufacturers would never adopt such an approach due to the significant increase in production costs. Burson Audio on the other
hand knows that only our level of quality control can produce opamps worthy of our badge. Only our level of quality control can produce the best
Opamp in the market.

Listening Impression
To Team Burson, listening to an IC opamp is like listening to a grand concert through a key-hole, or admiring Mona Lisa on a stamp!
The resolution and texture of our Burson Op-amp completely surpasses IC opamps. Compared with any IC opamps, it provides a fuller texture with
more refined detail. At the same time the bass is well controlled and very punchy. Double bass can now clearly take shape on a very
three-dimensional sound stage. Classical music reproduction becomes much more realistic where the string section becomes a group of individual
musicians rather than just a group. All in all the Burson Discrete Op-amp is a very listenable and engaging performer. It will bring pure music to your
soul, without listening fatigue to your ears.
